Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00053 | $0.01275 |
| Opus 5.5 | $0.00021 | $0.00510 |
| Sonnet 5.5 | $0.00011 | $0.00255 |
| Haiku 4.5 | $0.00005 | $0.00128 |
Grade A, and why
kx-handlebars scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 2mo ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

KX Dashboards — Handlebars Templates
Templates in KX Dashboards are Handlebars 4.7 strings stored as JSON string values. The most common locations are Template, CustomTooltip, TooltipTemplate, and advancedTooltip. This skill uses progressive disclosure: the core syntax, context rules, and common mistakes are here; the full helper catalog and the copy-ready template galleries live in reference/.
Reference Files
| File | Read it when you need… |
|---|---|
| reference/helpers.md | The full built-in helper catalog — every String, Number, Comparison/Logic, Array, and Date/Time helper with usage and examples. |
| reference/templates.md | Copy-ready template snippets — per-component tooltips (Datagrid, ChartGL, Heatmap, Gauge/Bullet, Radar, Chart3D, OfflineMap), Datagrid column cells, Text/KPI tiles, and Heatmap node labels. |
Core Syntax
| Expression | Output |
|---|---|
{{col}} |
HTML-escaped value of col |
{{{col}}} |
Unescaped raw HTML — use for HTML content in cell templates |
{{#if x}}…{{/if}} |
Conditional block |
{{#if x}}…{{else}}…{{/if}} |
Conditional with fallback |
{{#unless x}}…{{/unless}} |
Inverse conditional |
{{#each arr}}…{{/each}} |
Iterate over array or object |
{{@key}} |
Current key when iterating an object |
{{@index}} |
Current index when iterating an array (0-based) |
{{#with obj}}…{{/with}} |
Change context to obj |
{{lookup obj key}} |
Dynamic property access: {{lookup row fieldName}} |
⚠️ All templates are JSON strings — escape double quotes as
\"inside the template string.
⚠️ Context rules — the most common source of bugs
The Handlebars this context differs by component. Using the wrong pattern is the most frequent mistake.
| Component / field | Context shape | Access pattern |
|---|---|---|
Datagrid ColumnsConfiguration[].Template |
Current row object | {{colName}} or {{value}} for the current cell |
Datagrid Tooltip.Template |
Current row object | {{colName}} for any column |
Text Basics.Template (data source) |
Array of row objects | {{this.0.colName}} — this is the array, this.0 is the first row |
Text Basics.Template (ViewState only) |
ViewState map | {{vsName}} directly |
ChartGL Overlay.CustomTooltip |
Array of point objects | {{#each this}} then {{xAxis}}, {{yAxis}}, {{name}}, {{color}}, {{icon}}, {{width}} |
Gauge/Bullet Tooltip.CustomTooltip |
Array of data objects | {{#each this}} then {{dataCol}}, {{dataVal}}, {{title}}, {{data}} |
Heatmap Tooltip.TooltipTemplate |
Special named variables | {{_name}}, {{_label}}, {{_value}}, {{_color}} — no #each needed |
Heatmap Data[].NodeLabel.customLabel |
Current node row | {{colName}} — plain text only, no HTML |
Radar Tooltip.advancedTooltip |
Object with dataSet array |
{{#each dataSet}} then {{color}}, {{layerKey}}, {{layerValue}}, {{legend}} |
Chart3D advancedTooltip |
Object with points array |
{{#each points}} then {{xLabel}}, {{x}}, {{yLabel}}, {{y}}, {{zLabel}}, {{z}} |
OfflineMap layer Tooltip |
GeoJSON feature properties | {{propertyName}} directly |
SelectionControls labelTemplate |
Current item row | {{colName}} |
BasicComponents Image Template |
Current data row | {{colName}} |
PieJS PieceLabelTemplate |
Current segment row | {{colName}} |
What ships with it
2 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
What this file has done since we first saw it
Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

kx-handlebars is a skill published in the GitHub repository KxSystems/kx-skills (22 stars, last pushed 22d ago), licensed Apache-2.0. It adds 53 tokens to every session and 1,275 once invoked, about $0.0002 per session on Opus 5.5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
